installation of GNU top

[Andrew S. Chipalyuk]

Hello!

I had tried the GNU top (top-3.6.1) depot package (HP-UX 11i v3). In during porcess of installation i got the ERROR messages:

ERROR: Unknown owner and/or group for file "/usr/local/bin/top". SUID and/or SGID bit was not set.

After installation i tried to execute /usr/local/bin/top:

# /usr/local/bin/top
/dev/kmem: reading mpid: Bad address

I saw:

# ls -l /dev/kmem
crw-r----- 1 bin sys 3 0x000001 Mar 13 2007 /dev/kmem
# ls -l /usr/local/bin/top
-rwxr-xr-x 1 root sys 141588 Oct 19 17:10 /usr/local/bin/top

I changed mode of file:

# chmod 2755 /usr/local/bin/top

And i executed:

# /usr/local/bin/top
/dev/kmem: reading mpid: Bad address

The ERROR stayed.
How i can remove cause of ERROR? Why did ERROR happen during installation process?

Why is GNU top better than HP's?

>changed mode of file:
# chmod 2755 /usr/local/bin/top

This sets the SGUI. You need chmod u+s,g-s.
Compare to /usr/bin/top.

>> Why is GNU top better than HP's?

# dmesg| grep Physical
Physical: 8368188 Kbytes, lockable: 6099064 Kbytes, available: 6927468 Kbytes

i.e. the physical memory is 8368188 Kbytes, whereas /usr/bin/top shows:

Memory: 238668K (78820K) real, 463036K (161672K) virtual, 6481420K free Page# 1/5

>>Compare to /usr/bin/top.

# ls -l /usr/bin/top

You can also get this from SAM.

>-r-xr-xr-x bin ... /usr/bin/top

It appears your foreign devil top wants to use SUID to do its work. Is this something you trust?
Did you try "chmod u+s,g-s"?

hi,

you can also try glance.

e.g.

SRV2:home/yogeeraj>glance -m

Is it proprietary/commercial software?

[Andrew S. Chipalyuk]

>>You can also get this from SAM

I havn't found this in my SMH (11i v3).

>>It appears your foreign devil top wants to use SUID to do its work. Is this something you trust?

I need to watch using of physical memory. :)

>>Did you try "chmod u+s,g-s"?

# chmod u+s,g-s /usr/local/bin/top; ls -l /usr/local/bin/top
-rwsr-xr-x 1 root sys 141588 Oct 19 17:10 /usr/local/bin/top

And:

# /usr/local/bin/top
/dev/kmem: reading mpid: Bad address

[Yogeeraj_1]

hi again,

which version of HP-UX are you running? What type of installation is this?

revert

kind regards

Yes. There is a trial version of glance with HP-UX.

>I haven't found this in my SMH (11i v3).

Under SAM it was under Performance.

/dev/kmem: reading mpid: Bad address

Ok, it doesn't work anyway.

Hi,

Try,

# /usr/contrib/bin/machinfo

Two thoughts:

1) top is the wrong tool to monitor overall physical memory consumption. It reports user space consumption/status only. (Hence why the Real [actual RAM] in use doesn't match the actual physical memory on the box in most cases -- first, the system will always need some for itself and second, most times you look you aren't at 100% utilization anyway). Don't blame the native top for not reporting what you want -- it isn't intended to do so. Other tools (such as Glance as mentioned) are better suited if you want to monitor overall RAM usage on the system.

2) Whatever GNU top is doing, it sure looks to me like it is trying to use /dev/kmem to go peeking through the kernel internals with some assumptions as to data structures. In your case, it certainly appears said assumptions are wrong. [This is why binaries which assume /dev/kmem is safe to go tromping through are inherently risky for compatibility.] Since you can't force a new kernel to be built with whatever GNU top is expecting, I doubt this ERROR is going away.

>>Try,
>># /usr/contrib/bin/machinfo

The machinfo show physycal memomry, but don't show using of it:

Memory: 8172 MB (7.98 GB)

Thank you!

>>Other tools (such as Glance as mentioned) are better suited

But Glance is commercial tool.
Is there HP-UX standard/free tool?
